摘要

天基稀疏阵实现地面运动目标指示具有很大吸引力.然而稀疏阵存在栅瓣

理论分析与仿真结果表明栅瓣会产生盲速和虚假目标.本文提出一种消除角度模糊影响的简单方法:首先对均匀稀疏阵阵元位置施加随机误差消除测速盲区;随后采用陷零空时自适应处理剔除虚假目标.仿真结果表明该方法稳健、有效.

Abstract

Ground moving target indicator (GMTI) using space based sparse array is attractive.Unfortunately

grating lobes come with sparse array.Theoretical analysis and experimental reuslts show that grating lobes cause "blind speeds" and "false targets".A simple method for mitigating the angle ambiguity effects on GMTI performance is presented in this paper.The element positions of uniform array are randomized to reduce blind speed zones.Then the so called "nulling space time adaptive processing (STAP)" method is used to suppress false targets.Experimental results illustrate that the method is robust and effective.
